EVALUATION OF VOCAL HEALTH, VOICE CONTROL AND SUSTAINABILITY IN VOICE TRAINING USING THE SPEECH LEVEL SINGING METHOD

This research investigates the effects of the Speech Level Singing (SLS) technique, a vocal training method, on vocal health, voice control, and performance sustainability. Developed by American vocal coach Seth Riggs, the SLS technique aims to enable singers to produce a more natural and comfortable vocal sound by minimizing strain on the vocal cords. The study evaluates previous research on the SLS technique to highlight its potential advantages over traditional methods in preserving vocal health, enhancing breath and voice control, and achieving a sustainable long-term performance. A literature review and document analysis methods were employed within this framework. The findings indicate that the SLS technique provides singers with the flexibility to produce sounds across a wide vocal range while minimizing pressure on the vocal cords, thereby supporting long-term vocal health. The study also reveals that the SLS technique makes significant contributions to improving voice quality through effective breath control and resonance. This technique facilitates the integration of the natural voice used in speech into singing, enabling singers to feel more secure in their stage performances and to reduce performance anxiety. SLS offers remarkable benefits for vocal health, particularly for singers in fields that demand intensive voice use, such as professional stage arts, musical theater, pop and rock genres. This research underscores the positive impacts of adopting modern and innovative techniques in vocal training on singers’ vocal performances and vocal health. The SLS technique stands out as an alternative method for achieving sustainable and healthy vocal performance in vocal training and inspires future studies on its applicability across various music genres.
